Solved, I think a) someone drops out of MIT and works on Eternity DDS to
the point where people want to dump money into it, assuming it is
a fundamentally good idea, and b) by using market based protocols which give
a financial incentive to people running stuff, there is a rush to set up
In my system, no one knows (ideally) who is actually storing the data, only
those on the edges of the system (who will hopefully only be known by
a logical address).

That sounds like an interesting idea. It is certainly far simpler to
implement than my suite of protocols.

You may have solved the problems of persistence in Eternity, and if users
are intelligent about picking addresses, you may have solved the persistent
and logical URN problem. Cool!
I'm not sure the problems of scaling to a full production system have been
though. Would usenet simply ignore the additional, and potentially highly
and non-readable traffic? alt.binaries.warez got punted pretty quickly.
scheme does not include any provisions for people to post active objects of
any kind, or market-based load balancing, both of which I consider critical
features -- people will overload any Eternity server they can find -- what
motivation would the overt owners of the server have to upgrade to handle the
USENET is also not quite as resilient as it used to be.
I may have an unreasonable bias against usenet, but I think any protocol which
upon USENET rather than just using it as one of many potential transport
is unable to scale. Certainly the performance of your Eternity implementation
be far from real time. Coupled with not providing dynamic objects of any
kind, I think
there are a large number of services which could not function in your system.
It's still has a lot of potential, and is actually highly feasible to
implement, which is
good. And you seem to be evolving it, which leads me to think any potential
will eventually be solved. It would be interesting if we could share
were common to both designs, such as a payment arbitrator or whatever.
Having multiple interoperable Eternity implementations would actually be
They could store data in each other, in something of a recursive auction

Letting the market decide where it wants to put its data seems like the best
